Wrath

Will say that he's cool, right before losing his temper. 

A demon formed from the sin of wrath and he personafies is perfectly. The flame burning inside him can be seen through his eyes. 

He hooks up with Lust because she'll take anything and he can let out his anger and energy~

His horns absorb the wrath in the world and grow bigger, the more they absorbed. At a certain point, he starts growing more horns on his head and down his spine.
